T0 WHQM IT vMAY CONCERN:

Be it known that I, JAY W. POWERS, of Evanston, in theV county of Cook,and State oflllinois, have'invented n new and useful Improvement inHinges; and I do hereby declare that the following is a. full, clear,and exnct description of the construction and operation of the same,reference being had to the annexed drawings, making e. part of thisspecification, in whoh- Figure I is n perspective view.

Figure t2 shows the parts or segments of which it is composed.

Figure 3, n transverse section of the hinge when in operation and Figure1, the seme when closed. I l

A B and C represent; the three pnrt-s of a triplicatehinge,united at aand a" .by the pins (Z and nl', inserted 'into their appropriatethimbles, in the usuel mannen-of joining butt-hinges. A and C aroperforated with holes Z Z Z Z, Z Z Z Z, for screws to secure the hingein itsnpplicntion -in use, A being joined to B at a, and B to G 'nt a",so that when closed the part B is folded betw-erm the others'. The partA is provided with n, fossn or depression, c, and at the sides of thisfossa. thimbles b b, through which a pin is inserted. The p'zlnt B hasa. slot 'o1"sinns, and thimbles e e also for a. pin.l The part Chase.slot, h. lD is n. com for regulating the movements :of the other` parts;.it consists of a. body, n, and aI head, o; m is n pin projecting fromthe sides of the body n,

at 'its end; is a. slot in the head o, having a. curved or parabolicform k is a round hole. Uniting these parts os shown in fig. 3, the caml) is passed through the slotf, and secured to the part B by the pinpassing through thimbles e-e and the hole k, While the slot z' receivesthe pin passed through the thimbles b b on the 4part A, the head restingin the fossa c, the small end of the body 'n being passed through theslot k on the part C, the pin m holding it 4in its place, and, es thehinge is opened nnd'shut, sliding bhind, or'n a. groove on the part C.When the hinge is shut, the parts rest in the position shown in-fig. 4.

` It will readily b e perceived that the operation of the com is suchthntvvhen the hinge is opened atthe joint a', the head of the camsliding in the fossa. c, forces the part B away frorh the part-A,allowing the door E to swing clenr from its post, frame, or casing, F,the corner, taking the direction shown by the dottedlinespp, ns

shown in iig. I; and on closing it the pin passes through the thimbles bb, and the slot z' forces the parts A and `:B together, soy thatWhen-applied to ny door or other thing to which it may be applicable, itisnot necessary that :the hinge come to the surface at either side, butmay be placed at e distance therefrom, within the wood or other materialof which the door or its frame is made, and' hence when the door isclosed be entirely concealed or invisible. i

I do not claim the invention of the triplicate hinge, for that may havebeen mede before; but whatI claim -ns my invention, and' desire tosecure by/'Letters Patent, is- 4 The com D, applied to a triplicatebinge, constructed and operating substantially as and for the purposesherein set forth.
